ORACLEASM-QUERYDISK(8)	   Oracle ASM Support Manual	ORACLEASM-QUERYDISK(8)

NAME
       oracleasm-querydisk - Display information about ASM disks

SYNOPSIS
	   oracleasm querydisk [-l <manager>] [-v] [-d|-p] <label>|<device> ...
	   oracleasm querydisk -h
	   oracleasm querydisk -V

DESCRIPTION
       The querydisk command queries ASM disks. It can display such
       information as whether a disk exists with a given label, whether a
       specific device is marked for ASM use, and what device a given label
       corresponds to.

OPTIONS
       -l|--manager <manager>
	   Specifies the manager device to be queried. Almost always
	   unnecessary, as only one manager device is in use.

       -v|--verbose
	   Verbose operation. This will print any debugging information.

       -d|--device
	   Display the device number for each queried label. Does nothing when
	   querying a device path.

       -p|--paths
	   Display device paths for each queried label. Does nothing when
	   querying a device path. Requires the blkid(8) utility.

       <label>
	   An ASM disk label to query.

       <device>
	   A device path (eg, /dev/sda1) to query.

       -h|--help
	   Display usage information.

       -V|--version
	   Display version information.

EXAMPLES
       oracleasm querydisk /dev/sda1
	   Display whether /dev/sda1 is marked for ASM use.

       oracleasm querydisk -d VOLUME1
	   If the ASM disk VOLUME1 exists, display its device number.

       oracleasm listdisks | xargs oracleasm querydisk -p
	   Determine device paths corresponding to each disk listed by
	   oracleasm listdisks. Requires the blkid(8) utility to be installed.
